Prose:

(noun) Ordinary speech or writing, without metrical structure.

Examples:

FROST
"After Apple-Picking"
For all
That struck the earth,
No matter if not bruised or spiked with stubble,
Went surely to the cider-apple heap
As of no worth.

Effect: When the lines of the poem aren't written in blank verse, the lines are emphasized because it's a common characteristic of Frost's poems to be written in blank verse. This could be interpreted as Frost trying to highlight his thoughts and questions regarding the theme of the poem.

SHAKESPEARE
King Lear
Kent:
I thought the king had more affected the Duke of Albany
than Cornwall. (I. i. 1)
Gloucester:
It did always seem so to us. But now in the division of the
kingdom, it appears not which of the dukes he values most,
for equalities are weighed so that curiosity in neither can
make choice of either's moiety.

Effect: Shakespeare uses prose in context to who is speaking and to whom the character is speaking to. These lines are taking place without the presence of royalty, such as King Lear and his daughters, and thus the use of prose helps the audience decipher the status of the characters. It also emphasizes the irregularity of the speech and proclamations that Goneril and Regan later make in this scene.
